Effect of occupational therapy using visual stimulation children with autism

Autism is a pervasive neurodevelopmental disorder that is characterized by deficits in social interaction and communication and restricted interests and/or repetitive behavior. Other commonly reported features associated with autism spectrum disorders (ASD) include sensory processing over- or under-sensitivity. The functional architecture of the visual cortex has helped shape the traditional view that visual input is processed serially, in a bottom-up cascade of cortical regions that analyze increasingly complex information. This view has been challenged by models proposing a simultaneous bottom-up and top-down flow of information in the cortex.
